MEANS FOR OILING OVERHEAD CABLES.

SPECIFICATION forming part of Letters Patent No. 686,521, dated November12, 1901.

Application filed April 22, 1991. Serial No. 57,007. (No model.)

To all whom it may concern.-

Be it known that I, CHRIS LARSEN, a citizen of the United States,residing at Crockett, in the county of Contra Costa and State ofCalifornia, have invented certain new and useful Improvements in Meansfor Oiling Overhead Cables, of which the following is a specification.

My invention relates to a device for oiling overhead cables used forcarrying powerful electric currents. At present it is the practice tooil such cables by means of a brush applied by hand.

The objectof my invention is to provide a simple device for oiling thecables in a cheaper and more expeditious manner.

My invention therefore resides in the novel construction, combination,and arrangement of parts for the above ends hereinafter fully specified,and particularly pointed out in the claims.

Referring to the drawings, Figure 1 is a Vertical longitudinal sectionof my device. Fig. 2is a perspective view of the tank. Fig. 3is aperspective view of the closure for the same detached. Fig. 4 is an endview of the tank, the closure being removed; and Fig. 5 is an enlargedinside View of the means for surrounding the cable as it passes throughthe bottom of the slits in the ends to prevent the escape of oil fromthe tank.

Referring to the drawings, 1 representg an overhead cable, and 2 a tankfor oiling the same. Said tank is cylindrical in form, having diametralslits 3 in its ends and a longitudinal slit 4 at the top connecting saidslits 3, whereby the tank can be moved up into position on the cable,the cable passing down through said slits. Said slits are then closed bymeans of a strip of metal 5 bent into proper shape, as shown in Fig. 3,the ends of said strip being passed down and fitting tightly in groovesformed by plates 6, secured upon the ends of the tank on opposite sidesof the slit. The strip 5 has formed thereon a funnel 7, through which topour the oil into the tank, and said strip is retained in position onsaid tank by a suitable fastening device 8. A faucet 9 is provided atthebottom of the tank for drawing off the oil when desired. At the bottomthereof near one end is attached a rope 10, by means of which the tankmay be drawn along the cable. A suitable weight 11, suspended froin'thebottom of the tank by a rod 12, is provided as a counterbalance tomaintain the tank in a vertical position.

It is necessary to prevent the cable coming in contact with the metal ofthe tank as the latter is drawn along, and for this purpose there isprovided at each end of the tank a fixed block 13 of wood having asemicircular recess to partly surround the cable, which latter iscontained in said recess and in a similar recess formed in an upperblock 14 of wood, the latter being firmly pressed down by means of twosprings 15 at the sides of the slit.

In operation the strip 5 is removed and also the upper blocks 14, andthe tank is pushed up into place, so that the cable passes along throughthe bottom of the slits formed in the ends thereof. The upper blocks ofwood 14 are then secured in place, and the tank is closed by insertingthe strip 5 in the grooves at the end of the cylinder. Oil is now pouredinto the tank through the funnel, and the device is ready for use.

I claim- I 1. In an apparatus of the character described, a tank havingvertical slits at its ends scribed, a tank having vertical slits at itsends and a longitudinal slit connecting said vertical slits, a removablestrip of metal for closing said slits, blocks carried by the tank at theopenings in its ends through which the cable passes and surrounding saidcable to prevent the escape of oil, and means for drawing the tank alongthe cable, substantially as described.

4.. In an apparatus of the character described, a tank having openingsat its ends to permit a cable to pass therethrongh and provided withmeans for permitting the 1ateral insertion of the cable into saidopenings, means for closing said tank after the cable has been soinserted, and means for drawing the tank along the cable, substantiallyas described.

5. In an apparatus of the character described, a tank having openings atits ends to permit a cable to pass therethrough and provided with meansfor permitting the lateral insertion of the cable into said openings,means for closing said tank after the cable has been so inserted, acounterbalance hanging from the tank to maintain it vertical, and meansfor drawing the tank along the cable, substantially as described.

6. In an apparatus of the character de- CHRIS LARSEN.
